# Place-holder article

This is a place-holder article while I build this website.
Here is some `inline_code`

, as well as a code block:

```
fn main() {
println!("Hello world!");
}
```

I want to write some inline maths $\int_0^\infty e^{-x^2}$ and formulas $$\frac{Df}{Dt} = \frac{\partial f}{\partial t} + \boldsymbol v\cdot\nabla f$$
